Viewing Waveforms, Vectors, and Pictures
7-8
The most efficient way to use line select is with the two-field display. When you use 2 Field sweep
and line select together, the selected lines are brightened in the two-field display.

Viewing a Vertical Interval
You can view a vertical interval using two methods: 2F sweep (expanded horizontally) and line select
(see Figures 7-8 and 7-9). In 2F sweep mode, you can view both fields at once. Expanding this display
horizontally (by pressing the
H Mag button) lets you see the vertical interval. With line select, you can
move through the vertical interval viewing each line separately. The indicator at the top of the graticule
shows which line you are viewing and from which fields, odd or even.
For best results, you can combine these two methods.
For example:
1. Press the
Blue
button and then the
Sweep
button so the 2F LED lights.
2. Position the waveform so the vertical interval to be viewed is over the five small sync
measurement lines near the bottom center of the graticule.
3. Press the Line Sel button and then use the knob to brighten a line in this vertical interval.
4. Press the
H Mag
button and position the waveform until you see the desired portion of the vertical
interval with two brightened lines. Note that when in H Mag, two lines are brightened.
5. Use the knob to brighten two selected lines. The indicator at the top of the graticule shows the
number of the left-hand line and the field number (odd or even).
6. To view the odd or even field, press the Field Sel button.
